In the aftermath of the Libyan Civil War, author and reporter Rory O’Keeffe worked at Choucha Refugee Camp, Tunisia, where he met members of the African and Middle Eastern diaspora, then he was based in Sirte, Libya – Ghaddafi’s birthplace and the city in which he was killed, bringing to an end the war fought to displace him. He travelled across the vast state, visiting its towns and cities, and meeting the people who fought in its war – as well as those who fled its bullets and bombs.
